杏温室栽培品种选择及配套技术研究

Varieties and Techniques of Cultivation of Apricot in Greenhouse

从温室内高接的42个品种中筛选出适宜在薄膜温室栽培的杏品种‘9803’和4个授粉品种。研究结果表明:9803杏的低温需求量为490C.U;温室内杏花芽分化的时期在果实采收后10～15d;温室内的适宜树形为纺锤形及延迟开心形;花粉的贮藏最好方法为纸包装加塑料袋密封贮藏,授粉方法为蜜蜂授粉,在授粉品种与主栽品种花期不遇的情况下可利用贮藏花粉进行人工授粉。温室栽培9803杏品种,在4月中旬成熟,比露地提早60d。

Experiments were conducted with42top-grated apricot varieties and s el ections under the greenhouse conditions.Results of observation and evaluation o f the integrated characters of the varieties and selections proved that the sele ction9803was the best one for growing under the greenhouse conditions.Its c hilling requirement was only490C.U;the period of flower bud differentiatio n in greenhouse was10～15days after fruit harvest.The appropriate tree-tra ining system for9803was slender spindle and postponed vase form.The fruit m aturity period of9803in greenhouse was in mid April,60days earlier than i n the field.Practice also showed that for artificial pollination the best way f or storage of the pollen was paper-wrapped and then sealed with plastic bag.
